1. Transfer Switch

Having a transfer switch is the most important accessory to have when owning a portable generator. It is this switch that allows for the connection of the generator to all large appliances to the house grid. This switch allows for one to make the connection without purchasing any other additional equipment. When purchasing a transfer switch, it is necessary to research the wattage, the type, and what is included in the kit.

It is also necessary to note that there are two types of transfer switches; automatic and manual switches.

  • An automatic switch as the name implies, automatically signals your generator to start up when the power goes out. The switch then connects your home to the generator allowing for it to begin functioning. When the regular power returns, it automatically shuts off your generator. This switch is best if you would prefer this process to be automated.
  • A manual switch requires you to do the work of an automatic transfer switch and manually connect the transfer switch to your generator. Overall, if you enjoy the process of manually turning on the generator, then the manual switch would be a better purchase. If you prefer to not have to worry about manually turning on the generator, then an automatic switch is the best purchase for you.

4. Maintenance Kits

Maintenance kits for portable generators can be broken down into two categories: oil and air filters. These two categories coincidentally, happen to be the areas of a generator that tend to malfunction the most.

As a portable generator owner, it is key to have on standby, a generator maintenance kit. One could leave the generator’s problems however, this will result in the inevitable demise of the motor and overall generator.

Tips for generator maintenance:

  1. Power up generator for 30 minutes every three months, although there are no electricity blackouts.
  2. Keep clean and covered your generator when not use.
  3. Make sure; there has a proper ventilation system.
  4. Using a Heavy-duty extension cord instead of a cheap/ light power cord.
  5. After using a portable generator, you should remove oil from the tank unless you are planning to run the generator recently. Reserved fuel in another container.
  6. Fill your generator tank with oil when running and Monitor oil level. If the generator has an automatic low oil shutdown, relaxed!
  7. Remember, don’t exceed the wattage limit. Try to lower the load of the generator. If a generator runs at its full capacity (100% Load) can cause unexpected shutoff. It also cuts its lifespan.
  8. The last point, use fresh oil and new air filter during long time power outages.

II. Generator Oil:

Anyone might be easily confused when buying generator oil for the first time. Because, generator and motor oils are the same. But here some factors should be considered before buying.

Why synthetic oil best in comparison to other generator oil types:

  • Synthetic oils used to lubricate engine components that work faster than traditional motor oil.
  • When the engine’s in contact part moves produces friction, Synthetic oil creates a protective coating that helps to lessen friction.
  • It keeps a clean engine and prevents building up rust and corrosion.
  • It also helps to reduce exhaust emission.
  • Synthetic oils are also highly resistant to thermal breakdown and viscosity.
  • Another significant factor is synthetic oils work fine in cold weather.

5. Fuel Stabilizer   

Having a fuel stabilizer is essential for the health of a portable generator. The stabilizer is designed to keep the fuel of the generator fresh at all times. In order to have a properly functioning motor within the generator, the fuel must be fresh or else the generator can be damaged and even worse, malfunction. All of the negative outcomes can result in the need to purchase another generator which will cost substantially more than ensuring the fuel is fresh.

Why you need a fuel stabilizer?

When a generator running for too long, the fuel becomes extremely hot. And the volatile components present in fuel composition become oxidized and forms new aggregates, which may cause corrosion and other damage. To prevent such a possible damage, you need fuel stabilizer—it helps to keep your fuel fresh and clean for a long time as well as your generator safer.

6. Muffler

Portable generators are loud. Anyone that owns a generator understands the pain of trying to sleep with the insanely loud sound of the motor in the background. Not only will the neighbors send their heartfelt appreciation, but it will be much easier to fall asleep.

It is necessary to look at purchasing a generator muffler extension. Owning one for a portable generator in the basement is a must have in 2020. Again, it is worth purchasing for the sake of the neighbors and beauty sleep.

Tips to keep quiet your generator:

  1. Install your generator far from home or campsite.
  2. Make sure; there is enough air circulation.
  3. Build a soundproof box, Place generator within it. Remember, do not cover the exhaust pipe.
  4. Try to lower the generator load. When the generator load increase, the noise increases as well.
  5. Set generator on sound-absorbing matt, cover the generator body by rubber. It will reduce generator vibration noise.
  6. Replace the old muffler, Install a new one.
  7. Play music at your campsite.
  8. Apply a water bucket method. This trick is simple, pretty useful, and easy to do. You may decrease around 6-8 db from the rated noise level. Use hose or any other flexible pipe, connect it to the generator exhaust pipe and other ends to a Large bucket of water. Make sure; no water gets into the generator.
  9. Generator Type: A portable generator is comparatively noisy in compare to inverter generator if you love to go camping. It would be better to carry an inverter generator Instead of a portable generator.

The two largest aspects to look at when purchasing covers are the materials the cover is composed of and how much area the cover will be able to cover. Durable materials such as polyester fabric ensure the highest quality protection possible. Discovering the area the cover will cover is also key as if the generator is not properly covered, then the entire purpose of having a cover is invalidated.

The upside to purchasing these covers is the cost. For purchasing covers, prices may range from 15-170 USD. The perceivable difference in pricing would be the area it covers. Nevertheless, it is imperative to purchase a cover for your generator.

The generator cover usually two types depends on their using purpose. If you use the generator only for a home during power blackouts. Rest of the time, it has no use, and store your generator in a storeroom, garage or yard. You might need storage cover.
